To oll-iolinmit may concern.:

lu it. loiown that l', Maaoiis ll. l'focic-` wooo, n citizen of. tlic United Stnten, and' rewident of the borough of Manhattan, city, i-oinity, nml State of Now York, have invented eertain new nml useful Improveineuta in 'l`ype-Writiiig Machines, of which the following is u apccilieation.

My invention relates to a ribbon mechanism for typewriting machines and more purtii'nliirli to un improvement. in the method for vuryiiii,r the throw ot' the. ribbon eiii'riei '.o lu'ini: ditlereiit '/.oiies of the ribbon inio use. and iii providing means for i-hanging the iiorninl position of the ribbon earl-ier and its dii'eetion of vibration when' stencil work in to be done.

My improvement may be applied to .aiiy .-tvle, of typeii'ritiiif.: machine wherein the rbboii may be ribrated to cover or to nneoi-ei' the printing line when the type keys :ii-e operated. la the present instance. l have shown the improvement in connection willi the well known Underwood typewriter, wliieh at present employes-i n ribbon mtu-haiiism similar to that shown in Patent No. 026.050 to l". A. Cook. Tn thin typewriter, as regularly constructed, the ribbon carrier is shifted as the pinten is shifted, so that the throw of the ribbon remains the same for both upper and lower ease poaitions. For stencil work with the construction as at present iis-ed, the lever and ribbon carrier are entirely disconnected from the key actuated mechanism. 'ff the pinten in shifted while. stencil work is being done the ribbon y i-iiri'ier will bo shifted ne iisniil, but if the., ribbon lHliould lie tiiiit or the eiiri'iei is not.i perfectly free on its guides. the eurrier owing.: to its being free and diseomieeteil is liable to i'eiiiuiii in the shifted position when' the platen returns to tlu` inirniul lower eunoj position.' lf this should oei-ur. the nexti type brought to the printing point willf .strike the ribbon. with the result thnt. the imprint. on tlie nteiieil will init lio perfect.'

.'lhe olijeet of my iiiiproienu-iit is toniiiin-i tuin the ribbon ea'riier eoiiueeted -lo andi iuider tho eoiitrol of the. key actuated |neili-l :iiiiuin ut. all times. 'l`hi.-I is ueiuunplished livl providing: the vibrating lever of the Cooki construction hereiiiliefoi'e referred to with' n n additioiinl actuating pin on the op iositel sido of the fiileriim, nnd in auch re'ntionl thereto thatI when opcrutirelv connected tot the vibrating universal bnr rame, the rib-i bon carrier will normally stand above ort ovo'r theprintiniz line. niul when the iiiii-l vernal lframe iii' `vibrate-ilA by the operation of the type keys the ribbon eari'ier Iwill bei moved away-from the printing line so as tof 'completely withdraw tie ribbon before tho type renc ies the laten and thus permit thc writing of atenei s. 'llie mechanism here shown and described; may be considered as typical ot" my improve'y ment. for itwill' be understood that. various equivalent structures may be employed in adapting the idea toy various typewriter con-v striietions.

tvpewritcr are shown as are needful in` illiutratinf.,1r my improvement.

G' s iows a section on line 6--ti in Fig. il.

Referring to the drawings, 1 reprei-ienta the frame Yof the typewriter to which the type bnr hanger segment 2 is secured. 'l'lie type bars 3 are pivoted nt 'lin the seg.:- ment in the well known manner. and are keV aetnnted in the usual way. The universul bar 4. in position to be aetiiated b v the heel of the type bar ll, is lsecured to the frame 5 which is pii'otally eonneted at ti to the roek arms 7 which are pivoted at S to the brneket il extending iipwiird from the base of the machine at the rear thereof. Extending' traino'ersely of the maeliine. above the vibrating frame 5 is the shift rail 10 which is ad pted for vertical movementI to shift the plnxienfrom lower to upper euse position. Near the renter of the"'Shift-"Edf is i-eeiired un iiriii bi-iieket 11. upon tliei'earwiii'dly extending.: ui'iii of whieh nt l2. in

'l`liiin far the parto deseribed ure of the lrognlnr Underwood.construction and operaltion. 'i 'lhe lever 13 in the biehrome ribbon `iiieehiiniiun. as regularly used, is ,n'ovided ,with iin iii'in ttl, extending upwiiii ly from ,the pivot. or fiilcrinn 12 and carrying two laetniitiiief pins 1T, 18, one projecting from ;e :ieb side of the lever, the pins being nrranged substantially in a radial line from the fulciiim, but. the pin 1T is located closer ln the drawings only suehlparts of the.`

tto the fiilerum than the pin 18, so that when' fthe lever is vibrated by actuation of the pia .-1T the throw of the ribbon carrier will be greater than when the lever is vbrated by `tho pin 18. By thuii vibrating.r thelcver from pine or tho other ofthe pinii 17, 18, the zonen, 1, b of the ribbon R are brought to the printiinir line iis desired. In addition to the nctiipose the printing lineandpermit. the writ- -ing of stencils.

will he'secn that the pins ti', 1R, tti, of tlie` lever 13 will pass into'or out of the rcspeci tivo grooves of the U-shapcd iieces when the to make operative connection between the vibrating frame 5 and any one of the actu- ,atiug pins of the lever 18 to aetuut'e the rib- Ibon carrier in the desired manner.

.25 proiecting forwardly; and to the inside thereot'tire secured the U-shaped pieces 26, 2T which projcctlaterallv or transversely to the lever 13, and are fo ded to form. n alot. or groove to fit over the actuating pins 17.

ating'pins above mentioned 1 have provided` the lever with'unolher actuating pin 1t), lop-2, cated below thetuleriun or on the opposite# side of thel pivotfll, in such relation thereto that. when this pin is brought into operative position, the lever will bo moved to the po. sition indicated h v dotted lines in Fig. 5,2 thereby bringing the ribbon carrier up so that. the ribbon covers the printing litio when the type keys are at, rest. it, will thus be secu that'the normal position and direction of vibration of the ribbon carrier will bei changed so that at. each operation of a type key therihbon will be drawn down to ex- Any suitable mechanism may be employed 18.10 (see Fig. 6).

The grooves of the U-shaped pieces 26, 2?

are disposed parallel to the slide rods 23. It

block Q4 slides tip or down t iu rods 23; the.' length and location of the U-pieces with relation to the pins being such that only onel pin ut a time is in operative position in one of the U- ieccs.

When tljie slide block 24 is in the position; shown in Figs. 2 and 6, the U-picce 2T with be in operative position with respect to the: actuating pin,

i when in the position shown in Fig. t the U-f' piece 26 will be in o ierative position with respcctto the pin 1 and in the iosition" sliownin Fig. 6 the -piece 27 wi l be in operative connection with the pin 19. It will be noted that the positions shown in` 1-`igs. ti, 4 and t'i represent. the posit-ions of the ribbon and carrier when the type bar is at the rintinp,` point. with the respective insI 1li 8 and 1t) in operative position. huita ie 8, tif the lever lll; 'hlhii hrated, n. lever provided with an arni conineeted to the carrier and un operatin'g arm The block 24 provided with a downward extension or arin 28, which carries n pin or -roller 2t)l adapted to titrin the slotted end 80 of the lever 31 which ispivoted at. 352 to the vbracketli-seeured to the, frame bracket D.

"lhe pin or roller 29 is inadc long enough to permitvthe vihratory motion of thc vibraiing frame 5 to take place without disconnecting` the slide block from the lever slott. The opposite end of the lever 31 is pivotally connected by a slot and pin connection at Zl-t with a rock arm 35 secured to the rear end of the rock shaft'. 36, which extend through the front of the machine and has n rear bca ring in the depending bracket 37 secured to the frame of the mncliiiie. The front end of the shaft 36 carries n double ai'med lever 3S fixed to the shaft. and provided willi tinecr pieces 36 adapted to rock the shaft in either direction. In addition, the front end of the 'shaft is provided with a pointer 40 adapted to coiipcrate with an indicating arc 41, sccured to the front of the machine, and indieating by colors or letters the position of the slide block 24, thus inforinng the operator whether the ribbon vibrating mechanisni is in iosition for writing, black, red or stencil. n order to properly iosition the slide block 24 and retain it in.t ie adjusted position an arc-shaped arm 42 is secured to the shaft 86 near the bracket RT. The outer circular portion of the arin is provided with. V-shaped notches 43 into which the V-I shaped end of the detent. spring -tt is adapt ed to drop, and thus position and hold theI slide block 2t in the desired operative posi-1 tion with relation to the actuating pins 17, 18 and 19 of the lever 13. i

It will readily be apparent that. other suit able devices may be employed to slide the block .l und locate the suine and also to indiente the position thereof to thc'operator. lt will also he npiarent that other means 5 than thc slide bloeit und pins might be eing ploycd to carry ont inv iden, and therefore y the claims herewith are notv intended to he limited to the spceilie structure shown.
